Intelligent early warning device for high-altitude falling objects

Abstract

The invention discloses an intelligent early warning device for high-altitude falling objects, and relates to the technical field of safety early warning. The device comprises trigger devices, alarm devices, a detection device, a speed measurement positioning device and a central processing unit, the trigger devices are installed in a side road of a building, the distance between the installationposition of each trigger device and the building is ten meters, the alarm devices are mounted at the top of the side wall of the second-floor of the building; and the four trigger devices and the fouralarm devices are evenly distributed around the building. The detection device and the speed measurement positioning device are both installed at corners of a building. The detection device and the speed measurement positioning device are sequentially and alternately distributed according to the number of building floors. According to the high-altitude falling object early-warning system, the falling position of the high-altitude falling object is early warned in advance through projection of a beam lamp, pedestrians can be guided to evacuate and avoid in time, the early-warning range is wide, regular maintenance is not needed, meanwhile, the false triggering probability of the warning process can be reduced through the detection device and the speed measurement positioning device, and the early-warning accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of safety early warning, in particular to an intelligent early warning device for objects falling from a height. Background technique [0002] In order to meet the needs of urban construction, the number of high-rise buildings has gradually increased. The phenomenon of high-altitude parabolic objects is becoming more and more frequent with the increase of high-rise buildings, and small objects falling freely in the high-altitude will also cause casualties. Therefore, high-altitude falling objects cause great hidden dangers to the personal safety of urban residents. [0003] The patent (publication number: CN104601939B) discloses a method and system for monitoring high-altitude parabolic objects and eliminating their hazards. Four cameras are used to identify high-altitude parabolic objects, and a mechanical arm is used to drive a net to collect dangerous falling objects. This solution has the following defec...

The high-altitude parabolic phenomenon is becoming more and more frequent with the increase of high-rise buildings, and small objects falling freely in the high-altitude will also cause casualties. Therefore, high-altitude falling objects pose a great hidden danger to the personal safety of urban residents.

[0003] The patent (publication number: CN104601939B) discloses a method and system for monitoring high-altitude parabolic objects and eliminating their hazards. Four cameras are used to identify high-altitude parabolic objects, and a mechanical arm is used to drive a net to collect dangerous falling objects. This solution has the following defects: 1 .The protection range of the pull net is limited. If the falling object is th
